Spatial extent of the Deccan Traps in central and western India.
I am an igneous and metamorphic petrologist. I use major element modeling and thermobarometric techniques to study the origin and evolution of mantle-derived melts (basaltic primary magmas) that interact with wall rock and undergo fractional crystallization while ascending through the upper mantle and crust. I also study high pressure-temperature (P-T) metamorphism of rocks to understand the tectonic evolution of mountain belts by calculating P-T-time paths using thermodynamics, phase equilibria, and monazite chemical dating. The primary analytical tool I use is the electron probe microanalyzer (EPMA) that provides high-resolution images, elemental maps, and complete chemical analysis at the micrometer-scale resolution. Following are my research highlights:
